Question

1) Resolva usando a propriedade distributiva: a) 2 . (x + 3) = 12 b) 2 . (x – 3) = 12

Answer 1

Resposta:

A) 2.(x+3)=12

2X+6=12

2X=12-6

2X=6

X=6/2

X=3

B) 2.(x-3)=12

2x-6=12

2x=12+6

2x=18

x=18/2

x=9

Answer 2

Resposta: a)2•(x+13)=12 2x+6=12 2x=12-6 2x=6 x=6/2 x=3

b) 2•(x-3)=12 2x-6=12 2x=12+6 2x=18 x=18+2 x=9
